16 Claims..

This invention relates to a cerebral palsy type of infants table and: chair, particularly toan infants table and chair which is provided with a separate attachment by which the chair is specially adapted for use by children suffering from polio, or children afflicted with a cerebral palsy condition, such as a spastic condition.

When people are recovering from or fighting the disease commonly known as polio, they require frequent and constant exercise of the muscles which are afflicted with such a disease. Furthermore, not only do the muscles that have been subject to such disease require a large amount of exercise but also the coordinating muscles of the body or the muscles in the arms or legs which Were not affected by such a disease also should be exercised consistently and, extensively so that all of such portions of the body retain themselves in good physical condition and remain supple and increase in strength equally. Frequently the processes of treatinginfants during their recovery from polio has been to put them in a bed and have themmerely exercise themselves as much as possible when lyin down, such as by pressing their feet upagainst afootboard. This exercise reachesonly a few muscles.

In many instances infants whoiare victims. of birth injuries may as a result have acondition, such as cerebral palsy, and which. may produce an involuntary muscular movement, or there may be very poor control action of certain muscles. Such infants need particularly tight or effective supports provided therefor sothat the infant can be properly and safely positioned, particularly when seated. In some instances it would be preferred to have a rigid seat support for such infant, whereas in other instances a certain limited amount of movement is, desirable. To my knowledge, no seats. are provided for children of this type except for somespecialseating devices that different individuals may have had specially built for one particular child.

The general object of the present invention is to provide a combined infants table and. chair which is particularly suited for use by infants suffering from any form. of cerebral palsy and which table and chair is characterized byits ability to be adjusted. to-the individual. child for or by whom the article will: be. used.

Another object of the invention is to provide an infants table and chair which is portable and which is compact when inoperatively positioned.

A, further obj ect of, the invention is. toprovide aseat which canbeeither rigidly supportedfrom the table or which may have limited. pivotal movement with relation thereto, as desired.

A further object of the invention is to provide a seat including a back, a base and footrest with all of suchmembers being adjustable angularly With relation to each other.

Another object of the invention is to provide an attachment for a, conventional infants table and chair wherein the attachment permits the table and chair to be used by an appreciably longer infant than the normal childs table and chair.

A further object of the invention is to provide a special typeofa support device for infants wherein thedevice is quite sturdy and adapted for use in the exercising of the child supported therein.

Yet another object of the invention is to provide a table and chair wherein substantially any size of an infant can be supported therein and be locked in and secured to. the seat.

Still another object of the invention is to provide complete support and positive positioning of an infant in an infants table and chair.

A further object of theinvention is to provide an inexpensive-but long lasting type of infants table and chair that is adapted to stand hard use.

The foregoing and other objects and advantages of the invention will be made more apparent as the specification proceeds.

Reference isnow directed to the details of the structure shown in the accompanying drawings,

3 wherein the combined table and chair is shown and indicated generally by the numeral 10. The table and chair it is provided with an auxiliary seat wherein the chair is adapted to support longer or older children therein and means are provided to position a child securely in the chair. The combined table and chair it includes a flat table top I l which is supported by a plurality of legs I2 with one leg being positioned at each corner of the top H. These legs 12 are pivotally associated with the table top and have braces 53 provided therefor, the inner or upper ends of which engage with socket holes [3 to retain the legs l2 in their extended positions. One end of each brace rod is pivotally secured to one of the legs 12. Suitable guides or channels M are provided for the free ends of the braces to slide in upon release of the braces l3 for collapsing of the legs l2, which braces resiliently bear against the channel. The legs 12 are pivotally secured to the top H by conventional hinge means l5. Preferably the table top I I has an apron formed thereon by means of members l6 which extend down from the table top H at the edges thereof and also provide vertically upwardly extending upper flanges it which outline the table top H. The socket holes for the free ends of the brace rods are formed in the members 15 and engage with bent end portions of the braces. The table top H has an opening i1 therein adjacent the rear portion thereof and this opening l! is of such size as to permit an infant to be received therein and be supported by a seat which is suspended from the table top H, as hereinafter explained.

As a feature of the present invention, the size of the opening H is made adjustable by means of an auxiliary table top It that is slidably carried by the table top l i and is of less depth than the table top l i but which is shown to be of substantially the same width as the table top I I. This table top it has a slot or opening I!) cut thereinto, usually from one edge portion thereof. This slot i9 is adapted to form one limiting portion for the opening I? so as to control the size thereof. By movement of the auxiliary table top it forwardly or rearwardly of the table In the opening ll is varied in depth. Any suitable means may be used to secure the auxiliary table top to the table top I l and such means are shown to comprise bolts 29 which extend through slots 2| that are formed in the surface of the auxiliary table top if! at spaced lateral portions thereof and extend forwardly and rearwardly of the table and chair device E0. The bolts 2!! carry wing nuts 22 on the lower ends thereof which protrude through the table top Q l and retain the auxiliary top in engagement therewith.

The device of the invention includes a chair or seat which usually is pivotally supported from the table top ll. As one embodiment of means for effecting this type of a support action, the table top l l is provided on its under surface with a pair of side support bars 23 that extend the depth of the device if] and which have a front support bar 2 1 and a rear support bar 25 extending therebetween. All of the bars 23 through 25 are positioned in immediate association with the opening I! for a purpose that will hereinafter appear and so that the seat can be supported by means of the support bars in immediate association with the opening H. A seat base 26 is pivotally supported from the side support bars 23 by means of support rods 2'! that pivotally engage with the side support bars 23 at the upper end of such rods 2'! and which engage with angles 4 28 that are secured to the lower surface of the seat base 25 and extend downwardly therefrom. The support rods 27 may be formed in the shape of U-shaped bails with the base portion thereof ex tending between and under the seat base 26 between the angles 28 carried thereby. Of course, suitable anchor means are provided in the side support bars 23 for pivotally supporting the rods 2'! and holes are provided in the angles 28 for passa e or threadin of the bars 23 therethrough.

Fig. 2 of the drawing shows that a plurality of pairs of slots 29 are formed in the seat base 26 adjacent the rear portion thereof. It also will be noted that each of the pairs of the slots 29 are grouped along one of the lateral margins of the seat base. These slots 29 are adapted to permit the adjustable positioning of a backboard 3i! which is provided for the chair of the invention. This backboard 39 is substantially vertically positioned in the device l8 and it extends from the seat base 26 up through the opening ll to a point appreciably above same. The backboard 36 also carries a pair of locking fingers 3i at its lower edge and protruding therefrom so that these fingers 3! can be engaged with the slots 39 to positively engage the two members to permit such backboard 36 to receive substantial forces thereon and directed rearwardly thereof Without moving.

One or more suitable bumper pads 32 may be secured to the rear support bar 25 to prevent scratching or marring the backboard 38 by contact with such support bar. Preferably, the side support bars 23, as indicated in Fig. 2 of the drawings, are recessed as indicated at 33 adjacent the rear margin of the opening ill in the table top H to limit the forward movement of the backboard 30 when it is positioned in the seat ii]. That is, the normal distance between the side support bars 23 is narrower than the backboard 3!] which must be more or less threaded through the recesses 33 into engagement with the seat base 26 for operative position in the device of the invention.

Another important element of the present invention is that a pair of head support blocks 34 are adjustably carried by the backboard 33 at the top thereof. These support blocks 3% may be substantially triangular in shape in horizontal section and they are shown as being secured to the backboard 30 by means of each block 34 carrying a pair of bolts 35 at spaced vertical portions thereof which bolts extend through slots 36 formed in the backboard 313. These slots 36 are substantially horizontally directed and each pair of slots, formed adjacent one side of the backboard 30, are parallel. The bolts 35 carry wing nuts 31 at their ends to retain the blocks 34 in a given position on the backboard when such wing nuts are tightened into engagement with such backboard.

The basic seat of the device of the invention usually is completed by means of a pair of hanger members 38 which are pivotally suspended from the angles 28 adjacent the front portions thereof. Usually these hanger members 38 have a kick plate or kick board 39 secured and extending therebetween. A footrest 40 is secured to the hanger member 38 and is adapted to extend normally therefrom. This footrest 4E] is pivotally secured to the hanger member 38 by means of pins 41 which engage with a series of vertically spaced holes 42 formed in the hanger member 38 so that the pins 4| can be sprung into or out of engagement with the holes 42 whereby the vertical position of; the footrestlll; with relation to the remainder of; the device can easily be varied. Obviously, anydesired type of; a. foot-. rest construction. maybe used in the seat-.of-t the invention. The angles which. th hanger members 38 form with the seat base 26 are controlled by means of a brace rod 43-.which is in the form of an inverted U-shaped' bail: and with. the upper ends of the brace rod 43ibeing engaged with slots 44, which are horizontally directed, and which are formed in the angles 28; The slots 44 have several seating recesses- 45. formed in the front portion thereof to engage with the ends of the brace rods 43. for locking the brace rods 43 and thus. the hanger members. 38,111- a desired angular relationship with. the seat base 26 Inasmuch as the seat construction previously referred to may have av slight pivotal or swinging action when operatively positioned, a pair of brace rods 45 are provided with one brace rod being engaged with each side support bar- 23. These brace rods 46' are adapted toextend downwardly and forwardly ofthe device Ill-from a rear portion thereof where one end of? each pivotally engages with the outer'surface of one of the side support bars 23. and the free ends of the rods can be snapped into engagementwith holes formed in the forward or front portion. of the angles 28. Hence the angularly positionedbrace rods 45prevent any pivotal movement of the seat and lock it in a desired position. for a rigid seat support, when desired.

When the brace rods 46 are disengaged from the angles 28, the rods 45 can be swung up along the outer surfaces of the side support bars 23 and their inherent spring action. will retain them in such a position wherein they donotinterfere with the collapsing ofjthe device for storing same. However, if: desired, locking recesses could be formed; in the side support barsfor engagement with inwardly; bent end portions. of the brace rods 4.6.

An especial feature of: the present. invention resides in the provision. .of-a base plate 47. which is carried by or superimposed on the seat base 25, and normally. extends forwardly andv rearwardly therefrom-,with relation toithe remainder of the seat. The base plate; is-provided; with a plurality of transversely directed. slots. 48, that are formed in therear portion. thereof. one of these slots 48; is adaptedto: be, registered. with any desired pair of, the slots 29. formed in. seat base 25 whereby the locking fingers 35!; of. the backboard 30 can; be threaded therethrough to f rther in he backboard an in. a sis/enc tion andaid in retaining the base plate and backboard and seat base together as. an integral unit. If desired, thefingers 31 could; engage only with one of the slots 48; toposition the seat; back, or with one pair of the slots 29,

secured; to the front portion. of the base: plate 41 in order to. suspenct a. kick plate and footrest therefrom. In. thisinstance, a kickboard or kick plate 52 ispivotally secured to.the front portion of the base plate 41'! by means of hinge means. 53. The kick plate 52 is provided with reinforcing or positioning angles 5.42 adjacent the lower or bottom portion thereof with one angle 54 being secured adjacent each lateral margin of. the kick plate 52. Each angle 54 is provided with a plurality of vertically spaced holes 55 therein. A footrest 56 is secured to. the kick plate 52 by means of a sheetmetal' member-'51 which has rearwardly directed cars 58 formed" on. the sides thereof. These ears 58 are adapted: to engage with a conventional-meansi' such as a. bolt. 59 which in turn engage with holes 55- in the angle 54 for securing the member 51 to the kick plate 52. It will be seen that the kick plate 52 is supported by the angles 54? bearing on the outer or forward edge of" the footrest 4.0a that is carried by the hanger member 38. of the basic seat of the device of the invention.

Fig. 7 of the invention shows; to a certain extent, the adjustments that are possible with the seat deviceof theinvention. In this instance, the footrests have been appreciably changed in their vertical position, and the backboard 30 is positioned at a different vertical inclination. However, once the seat is adjusted, it will be substantially rigidly positioned inanygiven manner. By adjusting the various screws and wing nuts that retain the movable portions of the seat in a given position, any desired adjustment can be made of the seat components after which they can'be locked in a givenposition.

In many instances it'is convenient to position a combined infants table and chair in a closet, or to store the table and chair temporarily when not in use, or use it when visiting or travelling. Thus it is greatly desirabletohave the seat and chair fold up so-that it can bea compact unit, when stored. In order to achieve this result, the legs 12 are adapted to be swung to a position substantially flush. against the lower surface of the table top H. Fig. 81. shows. how the legs l2 can be swung to.- an inoperative position withv one leg being adjacent. each lateral, margin of the device in. The seat of the invention can be collapsed by first; disengaging the brace rod 43 from the locking recesses 45 formed-i in. theslots 44v and sliding or pivotally swinging the kick plate 39 and footrest rearwardly. of" the device. [0 up in under the seat brace 26; Next the footrest 40 can be-swung forwardly or upwardly about the pins. 4| to a position substantially-flush against the kick plate 39. At the same time, or previous thereto, the brace rods 46? should; be disengaged from. the angles 28 and be swung upagainst the outer surfaces ofthe side support bars 23' where such brace rodsare entirely 0111101 the way and do. not interfere with the collaps ofthet remaining portions of the seat. Theactionpreviously referred to withv regards to the hanger members 38,and;k:ick: plate 3.9 canbecompleted andra compact unit formed; from. this :portion of. the seat. Thereafter, the assembly so-.f.ormed. can. be swung rearwardly of theseat aboutthe support rods 21 since the upper ends thereof. are pivotally carr e br the sid isupportbars- 23..

Fig. 9 of the drawing showsthatthebase plate 4-] is: swung. up into substantially superimposed position-with; relati-om to. one of the legs. I2- but h: base plate i! 152 sl ghtly. below. the apron memb of. t table; top-. The; kick. plate; 52

next should be swung forwardly and upwardly of the device I and the front portion of said kick plate 52 is adapted to be brought into adjacent relationship and substantially superimposed below and beneath another one of the legs I2 in its collapsed position on the device I0. The drawings also clearly indicate that the kick plate 52 is brought into a substantially horizontal position wherein it forms, in effect a continuation of the base plate 41 which previously has been swun into a horizontal position adjacent the lower portion of the table top I I. Any conventional means can be used to secure the device it in its collapsed position and to this end strap means 50 and SI are secured to the lower surface of the table top II and engage with any desired snap means on the seat base 25 and kick plate 52 to retain the seat in a given collapsed position.

Usually it is desirable to secure an infant tightly in the seat and sometimes this end may be aided by using'a strap 63 that may be secured to the auxiliary table top I8 adjacent the rear portion thereof by clips 64 that engage D-rings B5 on the top. The strap 33 is adapted to be brought about the front portion of the opening I! to bear against an infant positioned in the device I0. An infant positioned in the device I0 is prevented from sliding out through the seat provided therein by means of a crotch strap 66 which is secured to a ring 69 on the under surface of the seat base 26, or a ring I0 on the base plate 4'! at the front edge thereof. This crotch strap carries a clip 61 at the free end thereof which-is adapted to engage with a ring 08 that is pivotally secured to and hangs downwardly from the front support bar 23 on the rear surface thereof. The strap 03 may be secured to the article of the invention in a different manner, if desired. D-rings H are pivotally secured to the rear, lower surfaces of the seat base 25 for engagement with the strap 63 to tie an infant firmly in the seat. The strap-s can all be disengaged readily to facilitate washing same.

The construction shown in Fig. 10 is quite similar to the construction explained hereinbefore with the exception that the top of the table has slots formed therein for limiting and controlling the movement of the top plate on the table top. Thus a combined infants table and chair I00 is provided with a top IOI in which one or more slots m2 are formed. These slots I02 extend rearwardly of the article I00 and may be positioned at any desired portion of the table top IOI, usually about the same as that shown in the article of Figs. 1 through 9. A top plate I03 is slidably carried on the top WI and has bolts I04 extending therefrom which extend through the slots 502 and have nuts I05 secured thereto for retaining top plate I03 in a given position.

In some instances it may be desirable to form the back rest or backboard and the base plate substantially integral and Fig. 11 shows a seat construction wherein the seat base H0 is supported from a table II I in a pivotal manner and the seat base H0 has a plurality of slots II2 formed therein and extending therethrough at spaced portions thereof adjacent each side of the base I I0 and the slots I I2 are similar to the slots 29 formed in the seat base 26. An auxiliary seat or base plate I I3 provided may be of any desired length and carries a pair of angles I I4 that extend downwardly therefrom and are adapted to be engaged with the slots H2 for retaining the auxiliary seat H3 in a given position with relation to the seat base IIO. However, adjustable forward or rearward movement of the seat base II3 with relation to the seat H0 is still possible by use of the various slots I I2. A backboard I I5 is secured to the auxiliary seat II3 by a hinge device III; so that such backboard extends up through an opening i I! formed in the table I l I. Usually the backboard H5 is threaded through the opening Ill and a recessed portion II8 may be provided adjacent the rear portion of the opening II I to facilitate engagement of the backboard with the opening Ill. The recess H8 may be appreciably deeper of the table III than is the corresponding recess 33 in the device I0 to facilitate positioning of the back II-5.

While it is contemplated that the device of the invention will be adapted for conventional support of an infant therein and also be useful in providing specialized support for an infant, in some instances the device of the invention may be specially built just to provide special support. One modification of the construction of the invention which would be possible would be to eliminate the footrest and support means provided for the feet, as provided for the seat base 25 of the device previously described. Fig. 12 shows a modified construction wherein a seat base I26 is provided with an angle member I28 on the lower surface thereof adjacent each lateral margin of the seat and this angle member is provided with a slot I4 5 therein which has a plurality of seat recesses I45 provided at the front end of same. Thus a brace rod I43 can be adjustably engaged with the recesses I45 to vary the angular relationship of a kick plate I52 which is pivotally secured to an auxiliary seat I41. The seat M7 is supported on the seat base I26 as previously explained and the kick board or other similar device is secured to such auxiliary seat by a hinge device I53. Angles I54 having vertically spaced holes I55 therein may be provided for engaging with the ends of the brace member I43.

It will be appreciated that when desired for comforts sake, a pad may be associated with the seat portion of the device of the invention and this pad may be formed in any conventional manner and usually should be removable to permit the cleaning or washing of same.

From the foregoing it will be apparent that a seat attachment has been provided which can be secured to an infants table and chair in order to permit a longer or older child to be positioned in the chair. Normally such older child who would be using the chair would be a child who had suffered from some disease or physical impairment. That is, the child may have a cerebral palsy condition wherein there may be a spastic movement of the muscles with no control over such motion by the child. The chair is particularly suited for supporting and positioning such children whereby the child can be completely blocked up or secured in a chair whereby the child may be safely positioned in the chair and no attendant is required for the child at such time.

Furthermore, in some instances children who have been the victims of diseases such as infantile paralysis can use the device of the invention and secure effective support thereby and also the child can exercise in the chair without damage to the chair and with a proper exercise action being obtained.

Normally the device will be made so that it can be collapsed into a compact condition for storage or for carrying it around, as when visiting. Usually, however, the special attachment for the 9 chair is separate therefrom and can be attached thereto or removed therefrom as desired so that the seat may be used with -or without the attachment.
